Death of a Salesman addresses loss of identity and a man's inability to accept change within himself and society.
The play is a montage of memories, dreams, confrontations, and arguments, all of which make up the last 24 hours of Willy Loman's life.
For example, Willy cannot resign himself to the fact that Biff no longer respects him because of Willy's affair.
Rather than admit that their relationship is irreconcilable, Willy retreats to a previous time when Biff admired and respected him.
The more fragmented and disastrous reality becomes, the more necessary it is for Willy to create an alternative reality, even if it requires him to live solely in the past.
This is demonstrated immediately after Willy is fired.
The three major themes within the play are denial, contradiction, and order versus disorder.
Each member of the Loman family is living in denial or perpetuating a cycle of denial for others.
In this scene in the past, Willy can hardly wait to tell the story to his buyers.
He considers himself famous as a result of his son's pride in him.
